Specification of Letters Patent.

Patented Jan. 19, 1909.

Application filed April 18, 1907. Serial. No. 368,108.

To all whom it may concern:

lie it known that I, ALEXANDER T. BROWN, of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Gearing, of which the following is a s ecification.

My invention has for its object the production of a gearing which is applicable for use in motor-vehicles and other apparatus to effect changes of speed, and is particularly simple in construction and highly eflicient in use; and to this end, it consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is bad to the accompanying drawing in which like characters designate corresponding parts i in all the views.

Figure l is a sectional view, partly in elevation, of my gearing. Fig. 2 is a fragmentary view a portion of: the case. Figs. 3 and 4 are sectional views on lines A-A and BB, Fig. 1. Fig. 5 is a fragmentary view illustrating the means for selecting and shifting any one of the revoluble members or gears, the contiguous part of the frame of a motor-vehicle being also shown. F ig. 6 in an isometric view of the detached guide member illustrated in Fig. 5. Fig. 7 is an end elevation, partly in section, of the parts seen in Fig. 5. Fig. 8 is a detail view of one of the forks, and a part of the bearing portion of the other fork. Fig.9 is a longitudinal sectional view of one of the guide-rods for theforks. Fig. 10 is a sectional view on line C Fig. 8.

This gearing comprises generally a rotary element, a lurality of revoluble members, as gears, s iftable independently. of each other into and out of connection with the rota element, and means for selecting and shifti an one of the revoluble members.

In t e il ustrated embodiment of my in-' vention, 1 is a caseprovided with a removable top or cover, and 2,3 and 4 are rotary shafts journaled in the case, and provided with suitable revoluble members, as gears 5, 6, 7, 8, 9, 10 and 11, the shafts 2 and 3 being disposed in axial alinement, and ,the shaft 4 being arranged 2 and'B. 'One end of the shaft 2 is within the case 1 and is formed of angu ar crossrsection, and the contiguous end of the shaft 3 is journaled in a lengthwise socket her 8 and the s parallel to the shafts arra ed 12 in the shaft 2. The opposite ends of the shafts 3 and 2 project beyond the case 1 and are supported by suitable bearings carried by caps 13 and 14 screwing into cpenin s 15 and 16 in opposing walls 17 and 18 o the case. The shaft 4 is'arranged entirely within the case 1 and is journalcd at its ends in bearings carried by caps 19 and 20 screwin into openi gs 21 and 22 in the walls 17 an In. Opposing portions of the caps carried by each of the walls 17 and 18 are formed with cutouts 23 which receive a cylindrical part it of a locking member 25 screwing into, or otherwise removably fixed to, said wall, and consequently, said caps are pre- "vcnted from undue detachment.

The bearings of the caps 13, 14-, 19 and 20 for the shafts 2, 3 and 4 form no part of my present invention, and hence it is thought unnecessary to describe the same herein.

The revoluble members 5 and 6 slide axially on the end of angular cross-section of the shaft 2. These members 5 and 6 are of dissimilar diameter, the one 5 of smaller size being nearer the wall 17. Opposing sides of the members 5 and 6 are formed with hubs provided with annular ooves 26 and 27, and the opposite side 0 the member 5 is provided with a clutch-face 28. The memher 7 is of smaller size than the member 5, is interposed between the end of the shaft 2 and the wall 17, is provided with a face 29 for coacting with the clutch-face 28 on the revoluble member 5, and is fixed to the shaft 3 by suitable locking means, as rivets 30, (shown by dotted lines in Fig. 1) which enter grooves 31 extending lengthwise of the shaft 3 in the inner face of the member 7 and in the periphery of the contiguous portion of the shait 3.

As clearly seen in Fig. 1, the revoluble member 8 is constantly engaged with the member 7,.nnd is suitably fixed to the shaft 4, as by rivets 32, arranged within grooves formed in the o posing surfaces of the memaft 4 and extending lengthwise of the axis ofsaid shaft. The revoluble members 9and 10, which are of less diameter than the 'membe'rB, coact respectively, with the members 5 and 6, an arc mount upon an enlargement 33 of the shaft 4 and bear against opposite sides of a sectional washer 34, Figs. 1 and 4, which is seated in a circular groove 35 formed in the enlargeclutch-.

ment 33 between the ends thereof. Rivets 36 are arranged in grooves 37 extending lengthwise of the enlargement 33 from opposite sides of the circular groove 85, and 1n corresponding grooves formed in the internal faces of the members 9 and 10 and registering with the grooves 37. The revoluble member 11 is of less diameter than the members 9 and 10, is inte al with the shaft 4, and is formed of less iameter than the openin 22 for permitting vendwise movement of said shaft 4 when assembling or removing the same. Said member 11 constantly meshes with an intermediate revoluble member 38, Fig. 3, suitably journaled within the case 1 and adapted to be engaged by the member 6.

The shaft 4, and the revoluble members 8, 9, 10, 11 and 38 form a rotary power-transmitti element, and the members 5 and 6 are shlftable independently of each other into and out of connection with such element. Although the illustrated construction and arran ement of said element and shiftable revoluble members are particularly suitable for use with the remainln parts of my gearing, it will be understood by those skilled in the art that any other suitable rotary element and shiftable revoluble members may be used in said gearing.

The means for selecting and shifting any one of the revoluble members 5 and 6 preferably comprises a 39 and 40, suitably forks 41 and 42 havin elon bearing portions or hu s sli able on the rods 39 and 40, and also havin portions thereof mounted respectively in t e grooves 26 and 27 of the revoluble members 5 and 6, a rockshaft 43 extending through the wall of the case 1, means for connectlng the rock-shaft 43 alternately to the forks 41 and 42, and for controlling the movement of the rockshaft, and operating means for moving said rock-shaft axially, and for rocking the same about its axis.

In the referable construction of my invention, tlie guide-rods 39 and 40 are provided with a plurality of indentations 44, F' 9, arranged one in advance of the other, gig the passages through the cylindrical forme with lateral branches 45 containing holding-members, as balls 46, and also s rings 47 tending to force the balls 46 into t eindentations 44. Said indentations 44 and holding-members 46 facilitate the desired positioning of the forks 41 and 42 and prevent lateral displacement of said forks. Opposing surfaces of the bearing portions or ubs' of theforks 41 and 42 are provided with engaging means, as sockets .48, preferabl spaced a art from each other, the soc et on one ork bein arran d opposite to the socket on the ot er for fixed within the case 1 ted cylindrical plurality of guide-rods,

portions of the forks 41 and 42 are when the revoluble members 5 and 6 are in their neutral position, and the opposing sides, and

upper ends, of both sockets being open.

The means for connecting the rock-shaft 43 to the forks 41 and 42, and for controlling the movement of said rock-shaft consists, in the illustrated construction of my invention, of a rockingalrm 49 anda guidemember 50. Said arm 49 is fixed at one end to the rock-shuft 43, and is movable with said rock-shaft and within the case 1. The other end of the arm 4-!) moves freely in a direction lengthwise of the roc-lpshaft 43 into and out of operative engagement with the sockets 48 of the forks 41 and, 42, to se lent the predetermined fork, and also moves in an arc in a direction disposed at an angle to the first-mentioned movement, to shift the selected fork. This arm 49 is preferably provided with a lateral extension 51 having engaging surfaces 52 and 53 spaced apart from each other, and here shown as formed on opposite sides of 0. depending part of the extension 51. The guide-member 50, Fig. 6, is in the form of a segment and is provided with a passage 54 which extends through the top edge and the upper portions of the opposite lengthwise faces of the segment substantially midway between the ends thereof, and is adapted to receive the lateral extension 51 of the arm 49. One of the lengthwise faces of the guide-member is provided with surfaces 55 and 56 arranger] in the same vertical plane, and at opposite sides of the passage 54, and the other lengthwise face of said member is provided with surfaces 57 and 58 spaced apart unequal distances from the plane of the surfaces 55 and 56, and also arranged at op One wall 59 o the passage 54 thus extends laterally beyond the opposing wall 60 of said passage. I do not, however, limit my gearing to the arrangement of the surfaces 52, 53, 55, 56, 57 and 58 herein set forth, as the same may, obviously, be modified more or less without departing from the spirit of my invention.

In the use of my gearing,:the lateral extension 51' is alined with the passage54 when the revoluble members 5 and 6 are in their neutral position; thesurface 52 of the extension 51 is respectively surfaces 55 and 56 oftthe guide-member '50 when the revoluble member 5 is shiftedto efi'ect high, "and "intermediate, speeds; and the surface 53 of said extension is respectively engaged with the surfaces. 57 and- 58 of said guide-member when the revoluble memher 6 is shifted to effect low speed, and re verse motion. When the extension 51 is moved along the surface 57 and alined with the assage 54 for shifting the revolable memb f er 6 from its position assumed in? QSIEIL fecting low speed, to its neiitral said extension, at the limit of sum moveengaged with the v a l'ulcrtnn. to select the predvtcrtniucd incinher, and movable in another direction about an axis spaced apart l'roni the fulcrum. to shift the selected lnei'nbcr. substantially as and for the purpose described.

.2. ln :1 gearing, a rotary clement, a plu rality of rcvolublc members f-llllltllllt; independcntty of each other into and out oi connection with the rotary element, and means For selecting and shifting any one of the revoluble memln-rs, said means including shifting devices having opposing. surfaces thereof provided with engaging means, a member common to all of the shifting demenhengeges the wall 59 ot the passage 54, and is thereby prevented from further movement lengtl'iwise of the guide-member 50, until first moved laterally out of engagement with the wall 59. It is thus apparent that the wall. 59 facilitates the finding of the neutral position of the arm 49 when the gear 6 is shifted from its position assumed to cll'cct low speed, and also prevents the engagement of the rcvolublc members (i and 11, effecting reverse motion, until the arm 49 is moved laterally out of engagement with the wall 59).

To those skilled in the art it will be ap parent that the guideqncniber 50 is protected from dust and dirt, is in close proximityto vices and enacting with said engaging the forks 41 and 42, and is subjected to iineans respectively; a lever, and a pivotal connection between said member and the le ver, said lever being movable in one direction on a fulcrum spaced apart from the pivotal connection for moving said pivotal connection laterally, to select the predetermined revoluble member, and said lover being movable in another direction about an axis. to shift the selected member, substantially as and for the purpose speciticd.

3. In a gearing, a rotary element, a plurality ot' revolublc members shiftablc inde pendently of each other into and out ,of connection with the rotary element, and means for selecting and shifting any one of the revoluble members, said means including a guide, a lever movable relatively to the guide in one direction to select the prcdeterminc member, and movable in another direction along the guide about an axis spaced apart from the guide, to shift the selected member, and a second guide independent of the firstn'ientioned guide and extending in the szunc general direction as said first-mentioned guide, the second uide controlling movement of the lever refiatively to the first-mentioned guide, substantially as and for the purpose set forth.

4. In a gearing, a rotary element, a pluralit of revoluble members shiftable indepent cntly of each other into and out of conncction with the rotar element, and means for selecting and shi ting any one of the revoluhlc members, said means including a lever, a guide coacting with the lever intermediate of the ends ofithe lever, said lever being movable on the guide as a fulcrum, to select the predetermined member, and being movable alon the guide about an axis spaced apart l i om the guide, to shift the selected member,

minimum Wear, and that any distortion of the frame does not affect the guiding or controlling of the rock-shaft 43.

The operating means for the rock-shaft 43 consists of a lever 6t and a guide 62, the lever 61 being provided with a channel 63 receiving an arm (34 projecting from the rock-shaft 4-3, and being connected to said rock-shaft by a ivot 65 extending crosswise of the rock-shall. The. guide 62 is spaced apart from the rock-shaft 43 above the guide-member 50, extends in the samegem oral direction as the guideunember 50, is independent of said member 50am! is mounted upon a suitable support, as an arm 66, fixed to the frame 67 of the motor-vehicle, and also serving as a support for one end of the rock-shaft 43. This guide preferably consists of bars spaced apart and arranged at opposite sides of the lever 61 at a point intermediate of the ends of said lever, the surfaces of said bars alon which the lever (i1 is movable being spaced apart a uniform distance throughout their length.

Tn the shifting of my gearin the lever M rocks upon the opposing sur aces ofthe bars, forming the guide 62, as a fulcrum, and thus moves the rock-shaft 43 axially for forcing the arm 49 into engagement with one of the fbrks 41 and 4:2, to select the predetermined revoluble member which it is desired to shi .The lever 61 then swings alon the go do 62 about the axis of the rock-shaft 43, to shiftthe selected member. Reverse movements of the lever 61 return theselected member to its neutral position and disconnect the rock-shaft 4:3, or rather the LQQ, from the fork previously coacting th$ewi tl;.\Q
